Saliency detection aims to find the useful and attractive regions from an image. In many situations, there may be multiple objects in the image, and these objects may have equal attractiveness. Moreover, the appearance of pixels in one object may demonstrate large difference, which could lead to lose the object integrality when detecting saliency. To this end, this paper proposes a multi-saliency...
CGRA (Coarse-Grained Reconfigurable Array) is competitive hardware architecture for streaming applications due to its excellent tradeoff between programmability and efficiency. However, the efficiency of CGRA highly depends on how applications are mapped onto it with optimized operation placement and data routing. In the routing procedure, data are transferred through different processing elements...
As we are approaching the exascale era in supercomputing, designing a balanced computer system with powerful computing ability and low energy consumption becomes increasingly important. GPU is a widely used accelerator in most recently applied supercomputers. It adopts massive multithreads to hide long latency and has high energy efficiency. In contrast to its strong computing power, GPUs have few...
This research developed a mixed-integer mathematical model for a generic closed-loop supply chain network design (SCND), optimizing all three inherent dimensions of sustainability, namely, cost, environmental, and social impact, simultaneously. The proposed novel hybrid model is designed for a single period and takes into account some real-life characteristics of SC implementation such as multi-echelons,...
The production of regular clean fuels is faced with a problem of declining profit under more strict and costly environmental regulations. To satisfy the desire for higher profit and the firm requirements of environmental protection, it is imperative to improve the efficiency of energy systems within refineries. Over the past decade numerous attempts were made to enhance the energy system, addressing...
In this paper, we deal with special generalization of metric spaces by considering the distances between objects as gradual numbers. Firstly, the concept of gradual metric spaces is introduced. The new concept is a generalization of classical metric spaces and gradual linear normed spaces in the sense of Sadeqi and Azart. And then, basic concepts with respect to topology in gradual metric spaces are...
